MOTOR-GONG.

\ Application filed May 20,

To all whom it may concern:

Be it known that I, JOHN R. HAMILTON, a citizen of the United States, residing at Yonkers, county of Westchester, State of New York, have made a certain new and useful Invention Relating to Motor-Gongs, of

which the following is a specification, taken in connection with the accompanying drawing, which forms part of the same.

This invention relates especially to water motors and connected alarm gongs used particularly in connection with automatic sprinkler apparatus so as to produce a loud bell alarm when the apparatus comes into action in the event of fire or otherwise and supplies a jet or stream of water to operate the motor. In the accompanying drawing showing in a somewhat diagrammatic way an illustrative embodiment of this invention,

Figure 1 is a transverse section through the water motor; and

Fig. 2 is a section taken substantially along the line 22 of Fig. 1.. t

In the illustrative embodiment shown in the drawings the motor may comprise a sectional casing inwhich the casing cover 1 1S joined to the motor casing 2 at a point substantially above the bearings of the motor so that they are not in any way disturbed when the casing is removed and consequent derangement or cramping of the bearings is prevented. These two casing members are of course rigidly secured together as by bolts and a tight joint may be made between them as by the packing 3 indicated. The motor shaft 13 may be mounted in suitable bearings within the lower section or motor casing 2, these bearings 15 comprismg, if desired, anti-friction or roller bearing members 16 to minimize friction and which may be conveniently held in position as by the bearing caps 17 screwed in place. The wheel 11 may berigidly mounted on this motor shaft as by the key 18 engagingthe shaft and the wheel hub, and buckets l2 similar to the Pelton type maybe arranged on the wheel so as to cooperate most advantageously with the motor nozzle such as 9, preferably arranged in somewhat upwardly inclined position adjacent the bottom of the casing where it is not only supported by the permanently mounted section of the casmg, but is also more likely to maintain its continued clear and effective condition.

forated shield guide, such as 6, may be secured to the removable cap or otherwise mounted substantially annularly around this screen within the nozzle casing t forming the nozzle drain chamber 5. The supply pipe 10 may communicate with the chamber at any convenient point preferably adjacent the supporting wall as indicated so that the water or other motive fluid passes up around the shield guide and then through the screen before entering the nozzle, particles of dirt or the like thus being more certainly deflected into the chamber below from which they may be removed when the plug 7 is taken out.

It is desirable to provide forthe reliable and accurate support and alinement of the motor in connection with the gong or. other mechanical alarm device which is usually mounted on the outside of the outer wall 47 of the building. This may be effected by securing the gong support 41 to the outer face of this wall as by suitable expansion bolts and shields, such as 40, and rigidly securing to the gong support an .alining connector tube 23 which may as indicated be screwed into the-bearing collar 42 on the support. This alining connector tube which as indicated may extend entirely through the wall may thus provide a substantially rigid alining projection with which may cooperate the apertured collar 53 formed on the motor bracket 22 connected with motor casing as indicated. The motor bracket may be secured on the connector tube in any desired 7 way as by the securing or holding nut 21 so as to permanently lock these parts in position and insure the alinement of the motor with the connected operating mechanism of riveted or otherwise connected hammer pins 31 which also serves to support the hammers alarm signal produced. Also this type of hammer mechanism especially where it cooperates with the upper part of the gong allows the mechanism and connected motor to start and attain practically full speed be fore the hammers engage the gong at all or exert in this way any retarding action on the motor or driving connections. If desired, the hammer arms may be rigidly secured in any suitable way to the tubular.

gong shaft 27 as by a threaded nut 29 cooperating therewith and this shaft may be mounted to cooperate with antifriction bearing rollers in the bearing 36 mounted in the bearing collar l2 as indicated. The inher end 26 of this shaft may have screwed or otherwise secured thereto the coupling washer 25' having a square or other noncircular aperture therein so as to accommodate the alarm shaft 24, the inner end of which may engage a coupling 19 pinned or otherwise rigidly mounted on the motor shaft 13 and having a similarly shaped noncircular aperture 20 therein preferably so formed as to allow a limited angular dis placement of the alarm shaft with respect to the motor shaft so as to give some universal joint action in connection therewith.

Inassembling the device the gong support may be put in place on the outside of the wall and then the motor bracket and connected parts secured to the alining connector .tube as above indicated, and then the square alarm shaft may be inserted from the outside of the building and after it is inserted in the aperture 20 this. shaft may be cut off to length so as to be substantially flush with the outer end of the gong shaft and then permanently held in place as by the cap,28 which may be screwed on the gong shaft to permanently hold' these parts i in operative position, the outer end of the alarm shaft fitting loosely within the aperture as in the gong shaft. The gong 38 may be permanently secured as by the bolt 39 to the perforated gong casing 4A which is put in place by locking its alining or locking projections 57 around the cooperating projections 58 on the gong support adjacent the upper end thereof. The gong and easing may be permanently held in position as by bringing a suitable looking aperture 43 over the locking lug 45 formed at the bottom of the gong support,

these parts being held in position by a pin or other locking device 46 which if desired may be padlocked in position,
